Analysis of island flaps of distal pedicled sural nerve accompanying blood vascular for 21 cases of lower extremity soft tissue defects reconstruction / 中国基层医药

Objective To investigate the characterristics of distally based sural flap for the leg reconstruction.Methods Twenty-one patients with soft tissue defects in the instep,heel,ankle and distall one third anterior tibial region were analyzed.Results All flaps survived and healed with the affected area.Conclusion Distally based sural flap was reliable flap without sacrifice of major arteries.It can be used reliably for instep,heel,ankle and distal one third anterior tibial region.

Concentration of K~+ and Mg~(2+) in vitreous humor taken by alternative micro-sampling method from both eyes of rabbits for the estimation of postmortem interval / 中国法医学杂志

72h), the average deviations are over 15 hours. The average deviations of Equation 2 are almost all above 10 hours. The average deviations of Equation 3 are the lowest of the three.Conclusion The [K~+] and [Mg~(2+)] in the vitreous humor rises while the PMI extends. There are correlations between the concentration of K~+ and Mg~(2+) in the vitreous humor and the PMI. For the estimation of PMI, we suggest that the equation with R2 lower than 0.98, or with high average deviations should not be used. It seems that multiple regression equation could increase the accuracy of PMI estimation.
